Summary of the invention
The invention provides the method for large-diameter steel pipe girth welding supporting and regulating device and realization welding, solve in the past in large-diameter steel pipe butt joint ring seam welding process, operating efficiency is lower, difficulty is rotated during welding different parts, welding quality is easily influenced, also may bring the problem of potential safety hazard to operating personnel simultaneously.
The present invention is that technical solution problem is achieved through the following technical solutions: large-diameter steel pipe girth welding supporting and regulating device, comprise bracing or strutting arrangement and adjusting device, described bracing or strutting arrangement comprises base plate and is arranged on two pieces of gripper shoes on base plate, and described adjusting device comprises cross bar and is arranged on two chucks on cross bar.
Described two pieces of gripper shoes are respectively equipped with some rollers, and described roller equidistantly distributes on the supporting plate.
Described two pieces of gripper shoes are fixed on wherein one group of parallel side of base plate.
Described chuck comprises two card columns be fixed on cross bar.
Described two card columns are parallel to each other and perpendicular to cross bar.
Adopt above-mentioned large-diameter steel pipe girth welding supporting and regulating device to realize the method for welding, comprise the following steps:
(a), treat that the large-diameter steel pipe of butt joint ring seam welding is placed between two pieces of gripper shoes by boom hoisting by two sections, and make the docking of two sections of large-diameter steel pipes;
(b), start to carry out girth welding to two sections of large-diameter steel pipes, first junction relatively low for large-diameter steel pipe two side position is welded;
(c), two of adjusting device chucks are stuck on large-diameter steel pipe, then press down the other end of cross bar, large-diameter steel pipe is rolled, higher junction, original two sections of large-diameter steel pipe positions drops to lower position, now proceeds welding again;
D (), repetition step (c), complete whole girth welding.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) present invention employs an adjusting device makes all welding can realize at lower position, thus the operation that ladder carries out higher position need not be built, not only increase operating efficiency, also avoid and bring potential safety hazard to operating personnel, simultaneously, operating personnel can also be enable to carry out operation in comfortable position, be conducive to the quality ensureing welding.
(2) the present invention by installing roller additional on bracing or strutting arrangement, makes the rolling of large-diameter steel pipe more easily laborsaving, improve operating efficiency, the noise produced when simultaneously can also reduce to roll, and then create good working environment for operating personnel.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1:
As shown in Fig. 2, Fig. 4, Fig. 5, the large-diameter steel pipe girth welding supporting and regulating device of the present embodiment comprises bracing or strutting arrangement and adjusting device, bracing or strutting arrangement comprises base plate 1 and is arranged on two pieces of gripper shoes 2 on base plate 1, and adjusting device comprises cross bar 4 and is arranged on two chucks on cross bar 4.
Two pieces of gripper shoes 2 of the present embodiment are fixed on wherein one group of parallel side of base plate 1.
The chuck of the present embodiment comprises two card columns 5 be fixed on cross bar 4, when work, chuck is stuck on the tube wall of large-diameter steel pipe, utilize lever principle that large-diameter steel pipe is rolled, and in order to make chuck more easily be stuck on the tube wall of large-diameter steel pipe, two card columns 5 are vertically fixed on cross bar 4 by the present embodiment, make two card columns 5 be parallel to each other simultaneously.
Adopt above-mentioned large-diameter steel pipe girth welding supporting and regulating device to realize the method for welding, comprise the following steps:
(a), treat that the large-diameter steel pipe of butt joint ring seam welding is placed between two pieces of gripper shoes 2 by boom hoisting by two sections, and make two sections of large-diameter steel pipes alignment, adjacent;
(b), start to carry out girth welding to two sections of large-diameter steel pipes, first junction relatively low for large-diameter steel pipe two side position is welded;
(c), two of adjusting device chucks are stuck on large-diameter steel pipe, then press down the other end of cross bar 4, large-diameter steel pipe is rolled, the junction of two sections of large-diameter steel pipes that original position is higher has dropped to lower position, now proceed again welding;
